1972 Honda CB450K Fuel Caps, Seals & Tank Attachment Hardware

Inspect the filler attachment and cap mechanism on the tank on your 1972 CB450K before choosing a cap package. A seal or latch may address a smaller repair. Compare the included pieces, then assess front support cushions and emblem retainers at their own attachment points.

1972 Honda CB450K · Gas Tanks, Caps, Petcocks & Parts Buying guide

Select the cap package from the retained parts

The chrome cap supplies a gasket and hinge pin with E-clip. The matte-black cap also supplies its latch mechanism. A separate sealing rubber and chrome latch package offer individual repairs where the cap remains in use; match them against that actual assembly.

Parts to consider

Honda CB OEM Type Filler Chrome Cap ~ Replaces 17510-323-310 Chrome filler cap with hinge hardwareCap referencing Honda 17510-323-310, including gasket and hinge pin with E-clip. Compare the retained tank’s filler and hinge arrangement. A latch package is not named in these contents.View part Honda CB Gas Cap Rubber Seal ~ Replaces 17525-300-000 Sealing rubber for a cap kept in serviceSeparate gas-cap seal referencing Honda 17525-300-000. Compare the sealing outline and cap retained on the tank. Its application does not specify the seal arrangement of every replacement cap fitted during earlier work.View part Honda CB Gas/Fuel Tank Cap Latch Assembly Separate chrome latch repair packageChrome latch, return spring, mounting pin and C-clip are listed together. Check the cap’s latch attachment before choosing this package. It services that mechanism without identifying a supplied filler-cap body or gasket.View part

Compare latch fastening as well as color

The conventional chrome and black latch packages list spring, mounting pin and C-clip. The Joker Machine black package instead lists spring and alloy screw with nut. Compare the intended latch attachment to the retained cap rather than using the finish to assume the packages contain identical fasteners.

Check the tank’s other connections separately

The petcock specifies M16 × 1.5 and requires an outlet-thread check. Front cushions use reference 17611-283-010, sold each with two used per bike. Emblem nuts sell individually under their own references. None of those service locations is automatically renewed by a cap purchase.

Filler-cap contents and tank hardware decisions

Which cap choice expressly includes a latch mechanism?

The matte-black cap names latch, return spring, latch pin and C-clip, along with gasket and hinge hardware. The chrome cap names gasket and hinge pin with E-clip without itemizing a latch. Compare the pieces you will retain before adding a separate latch package.

How can I check the separate seal for a cap installed during earlier work?

Match the old seal and retained cap to reference 17525-300-000 and the required sealing outline. The description does not provide dimensions for every aftermarket cap. Resolve that direct fit comparison before ordering it for a changed filler arrangement.

How many tank-emblem clamp nuts come in one order?

The clamp nuts replacing Honda 87311-634-600 / 87311-516-000 are sold individually. Inspect the emblem attachments on your fitted tank and count the missing or damaged fasteners before choosing the quantity for your order.
